Given numbers are 234, 639, 391, 855

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(234, 639) = 16614

GCD(234, 639) = ( 234 x 639 ) / 16614

= 234 / 639

= 234

Step2:

LCM(9, 391) = 3519

GCD(9, 391) = ( 9 x 391 ) / 3519

= 9 / 391

= 9

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 234, 639, 391, 855 is 1
